Process crash via unchecked UTF-8 conversion
Published May 9, 2025 · Updated May 9, 2025
Improper invalid-input handling in gwenn libsql-sqlite3-parser 0.13.0 and earlier allows local users to crash a consuming process. The dialect/mod.rs from_bytes helper passes parser-controlled bytes to unsafe str::from_utf8_unchecked and constructs a String without validating UTF-8. Reachability requires a consuming application to pass invalid byte sequences into the parser; exploitation interrupts only that process, with no reported data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
